Question

How many liters of oxygen must be put in a flask at 25.5°C to have a pressure in the flask of 2.51 atm when you have 0.87 moles of oxygen?

Group of answer choices

6.21 L

12.51 L

8.49 L

10.87 L

Answer 1

8.49 L

Step-by-step explanation:

use the Ideal Gas Law formula

PV=nRT

V = volume

P = pressure

n = amount of substance

T = temperature

R = molar gas constant (≈ 8.314 J/(mol K))

V=(nRT)/P

V=8.49 L
